$?ECIFIGATION forming part of Letters Patent No. 551,242, dated December 10, 1895. Application filed July 20, 1895. Serial No. 556,566. (No model.)

To all whmn it may concern.-

Be it known that LWILLIAM WVALLAOE, of New York cityfin the county and State of New York, have invented a new and Improved \Vindow, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved window, which is simple and durable in construction and arranged to permit of readily cleaning the window panes on both sides from the inside of the room.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indiate corresponding parts in all the figures.

Figure 1 is a face view of the improvement with parts in section. Fig. 2 is a vertical transverse section of the same on the line 2 2 of Fig. 1. Fig. 3 is" a sectional plan view of the same on the line 3 30f Fig. 1. Fig. l is an enlarged side elevation of part of the locking device forlocking the sash and stiles together; and Fig. 5 is a transverse section on line 5 5 Fig. 1, of the improvement, showing the sashes swung downward.

The improved window is provided with a lower sash A and an upper sash B, of which the lower sash is provided on its sides and near the lower ends thereof with pivots G engaging the stiles D, fitted to slide in the usual guidcways in the window-frame E. The upper sash B is likewise provided on its sides and near the lower ends thereof with pivots C engaging a pair of stiles D also fitted to slide in guideways in the casing E. The stiles D are hung on the usual ropes or chains extending upwardly, and passing over pulleys F in the sides of the window-casingand carryin at their d ownwardly-depending ends the weights F for counterbalancing the stiles and the lower sash A. The stiles D for the upper sash 13 are similarly hung on counterhalancing ropes or chains F also provided with weights F 5 The upper end of the sash B is adapted to be locked to its pair of stiles .D by a looking device having a casing G, secured to the top bar of the sash A, and forming guideways for the bolts G and G2 extending to the ends of the casing, to engage keepers H and H attached to the pair of stiles D. The bolts G and G are provided with shanks or rods G and G, respectively, extending inwardly and carrying at their inner ends pins G and G respectively, adapted to be engaged by arms J and J, secured on a spindle J mounted to turn in suitable bearings in the casing G. The spindle J extends to the outside of the casing and carries at its outer end aknob J 3 adapted to be taken hold of by the operator to turn the spindle J so as to move the arms J and J in engagement with the pins and G", to draw the rods G and G", and consequently the bolts G and G inward toward each other and out of engagement with the keepers H and H, so as to unlock the upper part of the sash A from the stiles D. Springs I are coiled on the shanks G} and G" to press on the bolts 1 and G to hold the latter normally in an outermost position and in engagement with the keepers H and H.

The sides of the sash A are pivotally connected at or near their middle by braces K with the stiles D, each brace being lllltlfi of two links K and K pivotally connected with each other, and pivotally connected with the sides of the sash A and the stiles D D. Now, when the sash A is unlocked from the keepers H H in the stiles D, then the sash can be swung downward into the position shown in Fig. 5,'the sash turning on the pivot C and the downward inotion bein limited by the braces K,the links of which open, as illustrated in Fig. 5. The outer face of the pane of the windowsash can be conveniently cleaned or other- Wise treated from the inside of the room.

The upper sash Bis provided with a look: ing device the same as the locking device referred to for the sash A, and the sash Bis connected by braces K with its stiles D, the said braces K being similar to the braces K. On the lower cross-bar of the sash A is hinged a bar L, provided with an outwardlyextending flange L, adapted to engage a recess A in the top of the upper cross-bar of the sash A, and on this hinged bar L is pivoted a downwardly-extending arm L formed with a slot L adapted to be engaged by the knob J so as to lock the bar L in place, and consequently lock the two sashes together when in a closed position, as illustrated in Figs. 1 and 2.

Now, by reference to Fig. 5 it will be seen that the two sashes can be conveniently swung (ilownwardly and inwardly into an open position, so as to permit of conveniently cleaning the outer faces of the sashes whenever desired. By the arrangement described, the connection between the sides of the sashes and the stiles can be made with tongues and grooves, so as to form avery tight joint between the stiles and sashes, and thus prevent leakage and exclude the air, rain, snow, &e.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with the upper and lower sashes and the latches mounted in the top rail of the lower sash and. provided with a central opera-ting knob or turn button, of the bar hinged to the lower rail of the upper sash, provided on its lower side with a flange to enter a recess in the top rail of the lower sash, and the slotted arm or hasp pivoted to the free end of the said hinged bar to swing down and receive the said knob or turn button and be looked thereby, substantially as described.

The combination in awindow with the vertically sliding stiles provided with keepers their upper ends, of the sash hinged to the lower ends of the stiles, a casing seeured along the upper rail of the sash and provided with oppositely projecting spring pressed bolts engaging said keepers and having inwardly extending operating rods lying in parallel planes at their inner ends and there provided with pins and a central spindle having arms on its inner end engaging said pins to retract both bolts and provided with a-knoh or button on its outer end, substantially as described.
